ISPConfig 3 DNS Setup problems

I followed this guide here, but I'm having problems with the DNS part. When I go to CheckDNS, I get "NS list mismatch: registration authority reports that domain is hosted on the following servers: 'ns1.schwartznet.com; ns2.schwartznet.com', but DNS server ns1.schwartznet.com reports domain to be hosted on '[parameter not found]'. Please make sure that you configure the same DNS servers in registrar database and on your DNS". Is there something I'm doing wrong? Help would be greatly appreciated.

Have you used the dns wizard to add the domain? If not, I recommend to delete the domain and then add it again with the dns wizard to ensure that all nescessary records get added and all records are formatted correctly.
